Break-in schedule
If your vehicle is new or equipped with any
new power train components (such as an
engine, transaxle, transfer [AWD models],
rear differential [AWD models] or wheel
bearing), Lexus recommends that you do
not tow a trailer until the vehicle has been
driven for over 500 miles (800 km).
After the vehicle has been driven for over
500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km),
drive the vehicle at a speed of less than 50
mph (80 km/h) when towing a trailer, and
avoid full throttle acceleration.
■ Maintenance
● If you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load. (See “Warranty
and Services Guide”, “Owner’s Manual
Supplement” or “Scheduled Mainte-
nance”.)
● Retighten the fixing bolts of the towing
ball and bracket after approximately 600
